As in her earlier Grandfather Twilight, Berger has created a picture book dreamscape, full of radiant colors and intriguing possibilities. Alone with her doll in a playhouse, the young narrator receives an unusual visitor who comes calling ""in a carriage bright as the sun.'' The visitor's consort is a lemon-yellow lion who dines on blueberries and cream as the two girls play dolls and paint a rainbow. At day's end, the visitor departs into a glowing sunset, promising to return. Berger's skillful blending of the metaphysical and a child's inner life make this an inspired work of art. (3-7)
